ABSTRACT:
The disclosed device is adapted for placing a ferrite core onto an energized power distribution system cable and includes a pair of generally U-shaped core holders. Each holder receives a core half which is loosely retained within the concave portion of the holder by an elastomeric "O" ring. The holders are pivotally mounted at one of their end portions to opposite ends of a saddle member wherein the free ends of the holders, and therefore the core halves, are translatable into either abutting or open relationship. The length of the saddle member is selected so as to provide a stop which limits the maximum opening of the core holders. An eye bolt threadedly engages the saddle member along a threaded transverse bore therein wherein the threaded end of the bolt engages overlapping portions of the pivot ends of the core holders. An elastomeric sleeve surrounds the saddle member and the overlapping pivot ends of the core holders and urges the holders toward their abutting position. Flanges extend from the sleeve toward the free ends of the core holders to orient a pick-up coil within the device. The eye of the eye bolt projects from the sleeve for engagement with the hook end of a hotstick. The eye bolt is provided with a left-hand thread so that clockwise rotation of the bolt closes the core holders, and therefore the core halves, around the cable.
